Cloud computing authentication using cancellable biometrics

Abstract

Cloud computing has increasingly been a hot topic in the recent years and has achieved maturity. However security concerns are the hindrance to user acceptance of cloud computing systems. User authentication among them requires a high-guaranteed security since all protections rely on the mechanism. As such in recent years biometric technologies are becoming one of the key foundations of a wide range of secure identification and personal verification solutions. In a cloud computing environment, since control over security diminishes as data move dynamically, they present some problems related to the management of biometric data. To overcome this problems, in this paper we propose to use a cancellable biometric authentication system. In this concept a distorted biometric image, derived from the original, is used for authentication. Additionally a data hiding technique is used to embed demographic information in the biometric image. As a result a robust authentication is created by which the original biometric image is not exposed.
